Sampling in a Union of Frame Generated Subspaces
A new paradigm in sampling theory has been developed recently by Lu and Do. In this new approach the classical linear model is replaced by a non-linear, but structured model consisting of a union of subspaces. This is the natural approach for the new theory of compressed sampling, representation of sparse signals and signals with finite rate of innovation. In this article we extend the theory o...
متن کاملSubspace Detection from Structured Union of Subspaces via Linear Sampling
Lower dimensional signal representation schemes frequently assume that the signal of interest lies in a single vector space. In the context of the recently developed theory of compressive sensing (CS), it is often assumed that the signal of interest is sparse in an orthonormal basis. However, in many practical applications, this requirement may be too restrictive. A generalization of the standa...
متن کاملFrameness bound for frame of subspaces
In this paper, we show that in each nite dimensional Hilbert space, a frame of subspaces is an ultra Bessel sequence of subspaces. We also show that every frame of subspaces in a nite dimensional Hilbert space has frameness bound.
متن کاملSampling Theorems for Signals from the Union of Linear Subspaces
Compressed sensing is an emerging signal acquisition technique that enables signals to be sampled well below the Nyquist rate, given that the signal has a sparse representation in an orthonormal basis. In fact, sparsity in an orthonormal basis is only one possible signal model that allows for sampling strategies below the Nyquist rate. In this paper we consider a more general signal model and a...
متن کاملFinite Sampling in Multiple Generated U-Invariant Subspaces
The relevance in sampling theory of U -invariant subspaces of a Hilbert space H, where U denotes a unitary operator on H, is nowadays a recognized fact. Indeed, shift-invariant subspaces of L(R) become a particular example; periodic extensions of finite signals provide also a remarkable example. As a consequence, the availability of an abstract U -sampling theory becomes a useful tool to handle...
